Abstract (en)
[origin: WO9605779A1] A disposable dental prophylaxis handpiece (10) is provided having a rotor (90) with vanes (92) pivotally connected thereto. The handpiece (10) includes an entrance (30) for elevated pressure fluid and an outlet (40) for discharge of the fluid after contacting the rotor (90). The elevated pressure fluid passes from the entrance (30) into a high-pressure chamber (80). The high-pressure chamber (80) is in contact with inlet ports (74) accessing a cylinder (72) within the handpiece (10). The cylinder (72) supports the rotor (90) with a rotational axis (M) of the rotor (90) off center with respect to a central axis (N) of the cylinder (72). The elevated pressure fluid causes the rotor (90) and an attached output shaft (97) to rotate. This in turn causes a prophylaxis cup (160), coupled to the output shaft (97), to rotate. The rotor (90) includes a trunk (2) with a plurality of posts (93) extending therefrom and with vanes (92) connected to the posts (93) through hinges (94).
